If you plan to post a pic, ask yourself "Would this appear in an Astronomy Magazine?" If the answer is no, submit to /r/pics instead. What this means is that your self-taken photos of stars, planets, etc are welcome, but refrain from posting pics that are tangentially related to astronomy, at best.

The way I am doing it is I bought a cheap webcam 1080p still and took it apart down to the bare board no housing, no lens, nothing. Hot clued it to the lid side of a 35mm film canister and made sure the photo sensor was aligned correctly (Do this buy taping it on first and putting it in the telescope and using a laptop to see if the view is clear or somehow wrong. Fix it and make adjustment and mark it where it should be sitting (I used a pen and made sure the board was flush with the lid so I could just clue it right on top) then I cut the bottom of the film canister and secure the lid (My lid was lose because I had to stretch it make sure it didn't fall into my reflector scope (Hot clue again) and after that, slip it into the lens slot on the scope and have fun..

Cheap, easy and you can get some pretty good shots.. Helps if you have a GoTo mount too.

I modified a cinema lifecam for use with my scope. It's a cheap and easy way to achieve some a high resolution planetary imaging but it does have limitations, namely; No gain or fine exposure adjustment resulting in considerable difficulty avoiding over exposed images of bright objects (ie: mars, saturn). And, the naked sensor will be sensitive to UV/IR wavelengths with the stock filter removed necessitating the use UV/IR cut filter.

The need to use filters in conjunction with this cam to get acceptable images might negate it's low price.

Is there another currently available webcam that is popular for planetary imaging? I'm looking at stepping into planetary imaging in the next few months as Saturn comes to a better location to image at my location.

I know the philips Toucam is the 'gold standard', but since they are no longer made, they tend to fetch astronomical prices when they pop up on ebay etc.

Last I heard when I was researching this last summer was they were trying to crack the firmware to allow manual exposure setting, but it might be the chipset they used has on-chip autoexposure.

[Edit: I'm on a tight budget, so a $100+ cam is unfortunately not a feasible purchase]

If I still had the webcam, I'd show you a picture. It's so laughably simple!

Take any old cheapo webcam, and remove the lens. Really, that's the only important thing that you have to do - you want the CMOS (or CCD on newer ones) chip exposed, and not going through two lenses.

The end of a water bottle (or a film canister, which was mentioned above) fits perfectly into the aperture of a telescope, just like any old lens would. The beauty (?) of a water bottle is that you can just cut it in a way that will allow you to glue it to the webcam, it's easy. Got some testors model glue? Or, heck, even some of that crappy white school glue - it'll work just fine.

Nowadays, I use the NexImage, but it's pretty costly. And, y'know, I always thought the old CMOS webcam had better colour quality anyways!

Most decent amateur scopes provide t-threads which will allow you to attach a camera to the telescope via a $10-20 adapter. This is called prime focus as the camera replaces the diagonal/mirror/eyepiece and the light cone from the scope focuses directly onto the sensor. You don't get the magnification you do from a eyepiece.

A little more expensive is to buy the t-ring adapter mentioned above and an eyepiece projection kit for about $50. You put the kit into where the eyepiece goes, and drop your eyepiece in the kit, then attach your camera. You get better magnification, but eyepiece projection isn't always that great.

The cheapest of all is to take an old webcam and expose its sensor by removing the lens and any auto-focus mechanism. Then go to Lowe's / Home Depot and in the household plumbing section find something with a tube diameter of 1.25" (bring an eyepiece or your diagonal to be sure.) You can get one of these for $2. Cut the tube to length through experimentation, then sand the inside ($3 sandpaper) and spray paint with flat black paint ($1) to reduce internal reflections. Then attach it to the webcam and you can use that instead of an eyepiece. I did this with a Logitech Quickcam Pro 9000 and it worked pretty well.
